摘要
单一石料填筑大坝对料场开采质量和储量要求较高,而两种不同石料分区填筑混凝土面板堆石坝的关键在于设计、施工等环节质量控制是否到位。介绍了在贵州省岩溶区用两种不同石料分区填筑面板堆石坝所取得的成功经验。从坝体填筑质量检测结果、坝体沉降和脱空观测、面板裂缝情况等方面分析了质量控制的相关要点,可为今后在喀斯特地区采用两种石料填筑混凝土面板堆石坝提供借鉴。
Concrete faced rockfill dam filling with one kind of stone material has higher requirement on the quality and reserves of quarry. The key problem of partitioned filling of concrete faced rockfill dam with two kinds of different stone materials is the quality control of design and construction. The successful experience of using two different stone materials to fill a concrete faced rockfill dam in karst region of Guizhou Province was introduced. The key points of quality control were analyzed from the aspects of dam quality check results, dam settlement, empty observation and slab cracks. The research can provide references for con-crete faced rockfill dam filling with two kinds of different stone materials in other karst region.
